As you can see we have used
super keyword to call Person constructor from employee class.

💡Did you know?

When you explicitly call parameterized constructor with
super(paramerters), then complier won’t call no argument constructor of Parent class.

Usage of super keyword at method level

super keyword can be used to call method of Parent class. It can be used to specifically call method of parent class in case of method overriding.
Let’s see with the help of example:
We have
printName() method in
Person and
Employee class and we will
super.printName() to call Person’s
printName() method.
